The photochemical activity, pigment composition, and activity of antioxidant enzymes of leaves of legume plants under the action of biologically active substances (BAS) were analyzed. In pea plants on the N50+BAS variant, an increase in the content of chlorophyll a and b and carotenoids was found due to the suppression of photosynthetic activity, due to a decrease in the quantum efficiency of PSII. On the N0+BAS variant, the content of pigments in pea leaves remained at the level of control plants. Under these conditions, only a tendency to the suppression of photochemical activity of leaves due to an increase in catalase activity of leaf tissues was observed. Therefore, on the N0+BAS variant, pea plants were more resistant to the influence of stress factors. Whereas, growing bean plants on the N50+BAS variant caused an increase in their adaptability to stress factors, while photosynthetic activity was higher on the N0+BAS variant.
